1,000-light-year wide bubble surrounding Earth is source of all nearby, young stars

Posted by in category: space

“This is really an origin story; for the first time we can explain how all nearby star formation began,” says astronomer and data visualization expert Catherine Zucker who completed the work during a fellowship at the CfA.

The paper’s central figure, a 3D spacetime animation, reveals that all young stars and star-forming regions — within 500 light years of Earth — sit on the surface of a giant bubble known as the Local Bubble. While astronomers have known of its existence for decades, scientists can now see and understand the Local Bubble’s beginnings and its impact on the gas around it.

India Is Doing Space Travel, on a Budget

Posted by in categories: business, government, space

India is one of only a handful of nations that have sent probes to the moon and Mars. But the most impressive part of its space program is its cost-effectiveness. Unlike other government space organizations, India’s agency is extremely efficient, with the lowest cost-per-kilogram in the industry. Now India is throwing open its doors to private companies and raising its stellar ambitions.

Ukraine hit by ‘massive’ cyber-attack on government websites

Posted by in categories: cybercrime/malcode, government

Suspected Russian hackers left a message on the foreign ministry website, according to reports. It said: “Ukrainians! … All information about you has become public. Be afraid and expect worse. It’s your past, present and future.”

The message reproduced the Ukrainian flag and map crossed out. It mentioned the Ukrainian insurgent army, or UPA, which fought against the Soviet Union during the second world war. There was also a reference to “historical land”.

In a message to the Guardian, the foreign ministry’s spokesperson, Oleg Nikolenko, said: “As a result of a massive cyber-attack, the website of the ministry of foreign affairs and other government agencies are temporarily down.”

Black Hole at Heart of Milky Way Keeps Flashing and No One Knows Why

Posted by in category: cosmology

Sagittarius A* keeps flashing randomly on a daily basis. Astronomers mapped 15 years of radiation bursts to try to figure out why.

The supermassive black hole at the center of the Milky Way, Sagittarius A*, keeps releasing random bursts of radiation on a daily basis and no one can figure out what is causing it. Now, an international team of researchers compiled 15 years of data to try and solve the mystery.

The team, led by a postgraduate student named Alexis Andrés, mapped a decade and a half’s worth of gamma-ray bursts from Sagittarius A* using NASA’s Neil Gehrels Swift Observatory.

The Early Sun’s Rings Stopped Our Planet from Becoming a ‘Super-Earth’

Posted by in categories: physics, space

The sun was once surrounded by rings of gas and dust similar to those orbiting Saturn, a new study published in the journal Nature Astronomy reveals.

These rings played a vital role in the formation of our solar system and in the size and habitability of Earth.

The early sun’s dust and gas rings may have stopped our planet from becoming a “super-Earth,” according to the Rice University astrophysicists behind the new paper. “In the solar system, something happened to prevent the Earth from growing to become a much larger type of terrestrial planet called a super-Earth,” Rice University astrophysicist André Izidoro, said in a press statement.
